Preamp / Balanced Line Driver / Headphone Amp.

Thank you for purchasing your Aquarian Audio Products UPA-1 preamplifier. This product is

designed to be exceptionally robust in the marine environment while being a very versatile tool for amplifying

the output of our H2 hydrophones. It can also be used with electret and dynamic microphones. The UPA-1

has two gain stages. The first stage is variable; the second jumper-selectable stage adds 26 db with an

infrasonic filter. Using different combinations of these gain stages, the UPA-1 will provide the vital link

between your hydrophone or mic and any consumer or pro-level stereo or PA equipment. The balanced

output can also directly drive headphones. The waterproof and corrosion-proof housing, conformal-coated

circuit board and gold user-replaceable output jack will give the user the freedom to monitor underwater

sounds in harsh salt-water environments with confidence and ease.

Figure 1: Overview

Battery Installation:

The rubber front panel snaps securely into the hard plastic cover without any fasteners. All of the

components of figure 2 will pull apart from the cover together. To minimize stress on internal components, try

to remove the amplifier assembly by gently pulling it strait out from the cover. Try not to "pop" it out violently

as this will strain the output jack and battery wires and could shorten their service life if done repeatedly. The

front panel can be removed by hand if necessary, but it is easiest to place any convenient rod though the hole

in the rubber (see tool insertion point, Figure 1) and use this rod as a handle with which to pull. A nail is

included so that you have this tool immediately at hand.

A lanyard and safety line are packaged within the battery cover. Remove these, attach a 9-volt

battery, place the battery into the cover, then snap the front panel back into place. Take care to align the

amplifier board with the slots in the cover during assembly.

Notes: (1) If the front panel is not placed into the cover evenly, the gain-adjustment knob is designed to push out of the

rubber front panel to avoid stressing the amplifier board. If this happens, simply push the knob back into place after the front

panel is assembled. Be aware of this possibility so as not to loose the knob. (2) after assembly, look into the recessed input

jack and ensure that you can see the entire silver ring of the jack. If the front panel is not placed into the cover evenly, this

can get out of alignment. If necessary, you can correct it by pushing it into place with any convenient tool, or by removing

and reinstalling the front panel.
